Hydrocyclone is a simple mechanical device, with no moving parts, where solid particles are separated from liquid with very little head loss. As its name describes, it uses a cyclone or tangential injection flow process enhancing the centrifugal forces and moving solids outwards. The dispersed particles, move downwards in a spiral path into an underflow …
